The main reason its restricted to Matrix is the voltage difference. Tetrix uses a 12 VDC battery and Matrix uses a 9 VDC battery. While the Samantha module can use either voltage, the margins are lower with 9 VDC. A stall of a Matrix motor can bring the voltage down below acceptable levels for the Samantha. A stall of a Tetrix motor does not have the same effect.

The only power issues I've seen affect the Samantha module on a Tetrix system is poor battery connections. The Samantha power plug is adequate if you secure it with a zip-tie. Its typically the other end that's the problem. Using Anderson Power Poles or similar power connections alleviates this issue.
